It takes a very good luck to beat the casino and even then it is very rare, in the context of how to beat the casino actually no matter how smart and clever you are you still won't be able to beat the casino as long as you keep playing in it, because as long as you play you will still be faced with risks. So in simple terms in my opinion the only way to beat the casino is when you manage to get a number of wins and after that you stop completely from the activity and then secure it and also enjoy the money from the winnings, believe that greed will only bring you a lot of losses and regrets.
Even you have very good luck and win a jackpot that doesn't mean that you are beating the casino. Because while you are winning the jackpot prize at the casino, thousands of gamblers like you have already lost to the casino by wagering their money. So even you win jackpot that doesn't mean you able to beat the Casino cause they already gaining the prize from the others this the business.
So I don't want to say here that we will ever be able to beat the casino, because in reality our competition is not with the casino, our competition is actually with our luck and the luck of thousands of other gamblers.

Yes, but that is only if, for example, you have always lost before, the possibility is between two, namely between you achieving recovery or getting some profit, oh yes, in the context of beating the casino, I think we should first talk between individuals, I mean not as a whole, but in the end I quite agree with your opinion in the last paragraph which is that in gambling the real enemy is not the casino but our respective luck.
Most gamblers are not lucky or the casinos do not let them win despite having a lot of experience and we spend our time busy trying to win ourselves. Gamblers who lose their money to win jackpots and keep the casinos running are examples of people who are not willing to give up. Those gamblers will actually consider the casino as the enemy or they have no other option. And finally, will we say, we are losing to our luck. But I will not consider luck as the enemy and I can keep my gambling within a limit and within my method.
